To all whom t may concern:

' Be it. known that I, ROBERT SoRcfAN,f a

citizen of the United States, and resident showing the position 'of the closure when of the city of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Closures, of which the following is a specification.

rIfhe present invention relates to improvements infclosure caps formed of resilient material and adapted when arranged over the mouth of a bottle,.jar or the like, to yield under suitably'applied pressure and thereby snapV into engagement with a ridge or collar adjacent to the mouthQ of the bottle, jar or the like.

-The general object of the invention is to increase the effectiveness of hand operated closure caps in point of attachable, detach- .able and leak proof properties, by the pro- Y vision of a structure which will render the body of the cap rigid, without reducing the resiliency of the flange or skirt, and thereby distinguish the cap from others heretofore proposed and wherein rigidity of the body' was sacrificed to attain flexibility in the flange, to the end that in the act of applying the cap to a 'jar or the like the body of the cap underwent distortion, frequently displaced the gasket, and thereby caused leaka e.

To these ends the invention resides in reinforcing thedisk shaped body ofthe cap and so proportioning the length of the resilient flange or skirt to the diameter of the body of the cap as to permit of flexing the skirt sufliciently. to effect engagement thereof with the flanged neck of a bottle, jar or and to employ the rein'forcing'structure as a means for depressing the marginal portions o'4 the gasket around the edges of the mouth of the closure.

Other objects will appear and be better understood from that embodiment of the invention of which the following is a specification, referencebeing had to the accompanying drawings forming part thereof and in which:

.The container a which formsv nopart of like provided at its upper end with the neck 6, the outer surface of which is interrupted as by the presence of a collar 7,'tl1e uppersurface 8 of lwhich is continuous with the end of the mouth 9 and joins with the outer surface 10 and the inner surface E10 on aline at right angles thereto and thereby provides the sharpened edges 11. The base of the collar joins the outer surface v10 on a line at right angles-'thereto so that a shoulder 12 of appreciable size provided The cap which is designated generally by A Y n 'b is by preference formedthroughoutof metal and' consists of the central body portion 13 whichv conforms in contour to the mouth 9, which .in most casesis circular, and as shown inthe drawings is reinforced' by marginal portion of 'the body and disposed. so as to lie adjacent to the edge of the inner surface 10 'of the mouth and with a peripheral bevelled surface 9 disposed so as to extend downwardly and overlie the outer edge 11 of the mouth when thel closure is' positioned as shown in Figures 1 to 2. vln Figure 8 a slightly modified provided which is formed by in the inner face of the body 13 and disposed the same relation to the a rib which in'Figures 1to 7 iiicli'isiveV l the lform of; a depression 14 in the form of rib 15 is a depression central portion of 'the body as the depression 14. The provision of this construe-1v tion 'operates as a reinforcement against.

easy bending or flexure of the body 13. The

body 13 functions as one element of a Clamp,

the other element being provided by the end 8 of the mouth 9 and the clamp operates to 1 the clamping action is able to slight variations in the .the collars of di'erent containers.

compress the disk-like gasket whichas shownin Figures 4, 5, 7 and 8 is of slightly greater diameter than 'the diameter of the mouth and may consist of an intermediate layer 16 of fibrous material preferably pasteboard, conforming in area substantially 'to the area of the body 13, and an outer Ilayer 17 of waterproofk material as paper or rubber; an additional reinforce ment in the form of a metallic disk 18 may lbe provided for the body ,13 when interposed between disk 16 and the body and constructed so as to bear throughout on the inner surface of the body as shown in Figures 4 to 7 and Figure 8. When the gasket is clamped between the body 13 and surface 8, such as to compress theintervening portion of the gasket and the marginal portion of the gasket is bent around the edge 11 by the bevelled surface 9' and around the edge of the inner surface 10 by the depression 14, so that a positive seal at the bearing portion 8 and the marginal portion of the gasket is effected. This effective clamping of the gasket is not dependent upon any precise thickness of collar, because the bevelling of the periphery of the body 10, and cross sectional curvature of the depression cooperate to provide a flared socket-like structure which is adaptthicknesses of When in clamped or closed position the body 13 is held by a pair of oppositely dis` posed resilient metallic tongues or claws portions 21 are parallel with t ward and 19 and 20, which depend vertically downterminate in inwardly and upwardly bent portions 21, the 'terminals of which bear on the base .12 of the collar. rllhe tongues 19-20 and relatively short, so that a maxi` mum of resistance is offered to transverse proportioned in the that the portions 21 bending upon the part of the portions 21 under lthe pressure exerted thereon by the tension ofthe gasket when compressed.

JAnalternative form of claw terminal is shown '1n Figure 9 and indicated by 21'; in this connection it will be observed that the part 21 is rolled and formed' as a bead at at the end of each tongue and disposed so as tofextend upwardly and inwardlyand engage the base 112 of the collar.

rlhe tongues 'or claws are formed integral with the skirt 22 tegral with the body 13 .and the skirt is so dimensien of its width of -the tongues or claws would extend below if the body 13 were arranged to bear directly on the mouth 9. The gasket, however, is so proportioned in the dimension of its thickness that when arranged as shown 1n Figures 4, 5, 7 and 8 its presence will which is fo-rmed inf the .base ofthe collarl portions l tach either of the engaging end portions 21 from the base 12 is permitted without such bending on the part of these parts being transmitted to the body 13. Thus it will be seen that in view of the degree of clamping force exerted on the gasket when the parts are positioned as shown in Figures 1 and 2 only a relatively slight degree of effort, in most cases which may be applied directly with the fingers, is all that will be necessary to detach one of the claws or feet 19-20 whereupon the parts will occupy the position shown in Figure 5, which position corresponds to that which the parts will occupy in the closing of the container which is e'ected b engaging the portion 21 on the right in igure 5 to the base of the flange 12 and then pressing downwardly on the upper left hand portion in Figure 5 to edect the downward movement yof the tongue or claw on the left inthe same figure, which tongue or claw together with the skirt will be flexed and thereby tensioned during the downward movement of the portion21 over the outer surface of the collarV until the portion 21 moves into alignment withthe base 12 when the said portion will be moved to engaging position by the resiliency. off the tongue or claw 19. During this move-47V ment of the parts it will be seen that the body 13 remains rigid so that lateralmovement on the part of the gasket cannotoccur. This is of importance because if the body 13 yielded then its movement' would be imparted to the gasket with the result that the -joint between thesame and the bottle might be impaired. 5 l

Although l have shown and descrlbed an idea-ly embodiment of my invention it 1s to be understood that l am not to be limited the upper edge of the mouth of the bottle Y and having securing means adapted to Cof operate with parts of the bottle for holdlng the body portion against the bottle mouth,

edge portion of the. gasket upon and about the edge of said bottle mouth, the inner face of the gasket near its periphery being normally plane and extending beyond the outer edge of the bottle mouth before being -applied thereto whereby the annular bevel of the body portion causes a swaging of the gasket aboututlie outer edge of the bottle mouth. t

22 A bottlel closure comprising a body portion of disc I form having a depending skirt portion larger .than the bottle mouth adapted to seat-upon'the upper edge of the mouth of the bottle and having securing meansadapted to'coop'erate with parts .of the bottle for holding the body portion against the bottle mouth, Aand a compressible gasket in disc form against the inner side-oit'l the body portion, said body portion near its marginal edge having two opposite depending portions and having an annular crimped portion spaced inwardly from said depending portions forming concentric gasket retaining means for compressing and confining the marginal edge portion of the gasket upon and about the edge of said bottle mouth, 'the inner Jface of the gasket near its periphery being normally plane and vextending beyond the outer edge of the bottle mouth before.l being applied thereto, whereby said opposite depending portions of the body portion causes a swaging of the gasket about the outer edge of the bottle .'mouth.

In testimonyv that I claim the foregoing .as my invention, I have signed my name hereunder.
